In classic Outlook, restore the message area from View > Reading Pane > Right or Bottom; if the pane is already present but remains blank, test Outlook in Safe Mode to isolate an add-in.
1. Restore the Reading Pane
- Open the affected mail folder.
- Select View on the ribbon.
- Under Layout, select Reading Pane.
- Select Right or Bottom.
This setting applies to the current folder. To use the same layout elsewhere, select View > Change View > Apply Current View to Other Mail Folders and choose the required folders. ^1^
Select an email. Its body should now appear in the chosen pane. If the pane appears but is completely blank, continue below.
2. Test without Outlook add-ins
- Close Outlook.
- Press Windows key + R.
- Enter:
outlook.exe /safe
- Select OK, accept the default profile if prompted, and open an email.
If message bodies display in Safe Mode, an add-in is interfering:
- Go to File > Options > Add-ins.
- At the bottom, choose COM Add-ins, then Go.
- Record which add-ins are selected.
- Clear their check boxes—do not use Remove.
- Restart Outlook normally.
- Re-enable the add-ins one at a time, restarting Outlook after each, until the blank pane returns. Leave the responsible add-in disabled. ^2^
3. If Safe Mode is also blank
Create a test Outlook profile:
- Close Outlook.
- Open Control Panel > User Accounts > Mail > Show Profiles.
- Select Add, enter a profile name, and configure the email account.
- Select Prompt for a profile to be used.
- Start Outlook and choose the new profile.
If messages display under the new profile, the original profile is damaged. Continue using the new profile after confirming that all required accounts and locally stored data are available. Do not delete the old profile until any required local data has been backed up.

4. Repair Office if both profiles are affected
On Windows 11:
- Right-click Start > Installed apps.
- Locate Microsoft 365 or Office.
- Select the three-dot menu, then Modify.
- Run Quick Repair first.
- If the pane remains blank, repeat the process and select Online Repair.
Online Repair is more comprehensive and repairs the entire Office suite, not only Outlook. ^4^
If only one particular message is blank while other messages display normally, the broader profile and Office repairs are unlikely to be the appropriate first action; test that message in a browser or another mail client to determine whether its body content is available.
